chemistrytalk.orgA nucleus containing one proton and one electron orbiting it is the name derived from the Greek for ‘maker of water’, reflecting its reaction with oxygen to form water. Its atomic number is 1, and its atomic weight is about 1.008. The electron is held by electromagnetic forces and is described by quantum mechanics rather than a fixed orbit. Common sources summarize its structure, properties, and role in chemistry and astrophysics. As the simplest and most abundant element, hydrogen dominates many landscapes of science. It is a colorless, odorless, tasteless, and flammable gaseous substance.
